How to set up and use Zoom on Apple Watch

Zoom increases the magnification of the Apple Watch interface, making it bigger for those who need to see it more easily.

To better aid those who need greater visual accessibility, Zoom lets you set a default magnification level for the Apple Watch but also adjust it dynamically. For those with visual impairments or partial blindness, it can make what are otherwise small, hard to see screen elements bigger and easier to see.
